Torterra lifts its front two legs into the air and slams them down into the ground. When it does, two pulses of energy erupt from its legs for a moment. A crack then travels long the ground and towards the opponent. When it reaches the opponent, the ground under it begins to shake violently.

Ursaring slams both of its palms into the ground, causing the battlefield underneath the opponent to crack in half and open up. When the opponent falls inside it, the ground closes back up, trapping the opponent in the earth.

Trivia

This move caused an episode to be banned in Japan, due to the 2004 Chūetsu earthquakes having struck the country a couple of weeks before the episode in question was intended to air. Due to this, Earthquake, and the similar moves, Fissure and Magnitude, have not been seen or used in the anime since.
